Terminal blocks & terminal blocks
Terminal blocks, often simply called terminal blocks, are a proven connection element in electrical installations. They enable a safe and reliable connection of electrical wires and are used in both residential and professional applications. In our webshop you will find a wide selection of terminal blocks for various requirements.
Versatile solutions for electrical installations
Terminal blocks are used wherever cables need to be connected, extended, or distributed. Typical applications include lighting connections, junction boxes, control cabinets, and repair and maintenance work. Terminal blocks consist of several individual terminals and can be flexibly cut to the required number of poles.
Different versions for every need
Depending on the application, terminal blocks differ in design, material, and current rating. Versions with insulating plastic housings provide added safety, while brass contacts ensure good electrical conductivity. Our product range includes terminal blocks for various conductor cross-sections as well as for rigid and flexible conductors.
Easy assembly and secure connection
Installing terminal blocks is quick and easy. The stripped conductors are inserted and secured with a screw connection. This creates a stable, vibration-resistant connection with low contact resistance – ideal for a durable and safe electrical installation.
